Making MAbs: Bioprocess Advancements Challenge Platform Assumptions

by

Still the largest sector of the industry, monoclonal antibodies (MAbs) have dominated the biopharmaceutical stage for over 30 years. Some observers might think there’s nothing new to say about these molecules; others point to antibody derivatives as a more exciting alternative. But MAbs are far from an outdated technology. From biosimilar developments to cell-free synthesis to yeast display, immunogenicity improvements, and fully human antibodies — as well as improvements in process efficiency and cost reductions, as discussed herein — the…

The Therapeutic Monoclonal Antibody Product Market

by , and

Commercial development of therapeutic monoclonal antibodies (MAbs) began in the early 1980s, and by 1986 the first MAb product had been approved in the United States: muromonab-CD3 (trade name Orthoclone OKT3, marketed by Janssen-Cilag) for prevention of kidney-transplant rejection. Since its approval, therapeutic MAbs and antibody-related products such as Fc-fusion proteins, antibody fragments, and antibody–drug conjugates (collectively referred to herein as “MAb productsâ€) have grown to become the dominant product class within the biopharmaceutical market. They have been approved for…

Tracking Therapeutic Antibody Development in a Pandemic

by

The COVID-19 pandemic has generated a significant and rapid response from scientists who aim to develop drugs and vaccines in the academic, government, and industrial sectors. Such interventions are essential to containing SARS-CoV-2, the coronavirus that causes the COVID-19 disease. To inform and educate the public about global efforts to develop targeted therapies such as monoclonal antibodies (MAbs), The Antibody Society (TAS) and the Chinese Antibody Society (CAS) have designed and implemented a freely available online database called the COVID-19…

G-Protein–Coupled Receptors: Promising Targets for Antibody–Drug Conjugates

by , , and

G-protein–coupled receptors (GPCRs) are a large and diverse family of seven-transmembrane–domain proteins expressed on the surface of human cells. These molecules respond to external stimuli by initiating signal-transduction pathways that affect the expression of a large family of genes — which, in turn, regulate a range of vital physiological processes and functions. Figure 1 illustrates the general pathways of GPCRs. Without these proteins, humans simply could not survive: Without β-adrenergic receptors, we could not regulate our blood sugar, for example;…
